I have a form named "Requerimiento Presidencia". This form has a subform (SF4), this one has a subform (SF3), this one has a subform (SF2) and this has a subform(SF1).

I fill the selectBoxes: 

• "Requerimiento Director Area" in the subform (SF2)
• "Requerimiento Director RRHH" in the subform (SF3)
• "Requerimiento Director General" in the subform (SF4)

and the datas are saved successfully on the database. For example I fill the selectBox (SF2) thus:

But when the form "Requerimiento Presidencia" is loaded, all fields have data less selectBoxes from (SF3, SF2).

Any idea??
